< benchmark > (Or VAX Unit of Performance, VUP) The processing power normally attributed to a Digital Equipment Corporation VAX 11/780. Future VAX systems were rated according to this scale (e.g. VAX 8350's being 2.7 VUPs per CPU). A MicroVAX II is normally associated with 0.9 VUPs and at a later time the MicroVUP was coined to rate VAX workstations . The use of the VUP by Digital Equipment Corporation has been replaced with more standard benchmarks ( SPECint and SPECfp ) in the DEC Alpha processor systems.
